Add reviewer automatically based on condition not coming from changes

Is there a way to add in a Pull Request certain reviewer/s based on external parameters outside from is changed certain files?

Examples:

  • Add X reviewer if PR made from 08:00 to 17:00 and Y if PR made from 17:00 to 21:00
  • Add X reviewer if there is some file deleted
  • Add X reviewer each 10 PRs
  • Probability to add X reviewer of 5%
Solution

    Available pull requests events are the following:
